Random GoodHart: a newly discovered LAW Answered

I know this is kind of random, and I just now, moments ago, accidentally discovered this, but there is a GOODHART's LAW :-)

It states: once a social or economic indicator or other surrogate measure is made a target for the purpose of conducting social or economic policy, then it will lose the information content that would qualify it to play that role.

This almost sounds like a parallel to the famous Quantum Mechanics rule of effecting the state of a particle by observing it.

Your clever law is a variation of other law "The implementation of a system changes the conditions that gave rise it, so is automatically outdated".

Years ago I discovered by myself a law that really did exists, that is "when a quantitative variation is large enough, it becomes qualitative". IE: you have an apple, then you get five new apples, it is cuantitative. But if you get a ton of apples, it is qualitative.
